It works in the sense that I can run genmap from the command line with
python2.4, but I still get the same errors in error.log, and a 501 when
calling genmap.fcgi from the browser:
[Mon Feb 12 10:43:09 2007] [warn] FastCGI: (dynamic) server
"/var/www/mapit/genmap.fcgi" has failed to remain running for 30 seconds
given 3 attempts, its restart interval has been backed off to 600 seconds
I wonder if "dynamic" is the right mode to run genmap? If I understood
that right there are three modes to run fast-cgi scripts, do I have to
choose a particular mode?
Anyway, I wrote a small test script (with code stolen from genmap.fcgi)
to see if fast-cgi generally works for me, and it does.
P.S. this is the test program that works fine as fast-cgi script.
#! /usr/bin/python -O
import os, sys
req = fcgi.FCGI()
print "Content-Type: text/plain"
